METHOD OF GASIFICATION PROCESS SIMULATION FOR RESIDUAL LIQUID ROCKET FUEL AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2015 - IPC G09B25/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to simulation devices and can be used in modelling of processes of gasification of liquid fuel residue in tanks of separated stages (SS) of launch vehicles (LV). The device for simulation of process of gasification of residue of the liquid component of rocket fuel in SS tanks of LV stages contains the experimental unit (EU) in the form of the simulated tank with the pan for gasifiable liquid in tanks, temperature and pressure sensors, cylinders with pre-treated gas, the electropneumatic valve, the logic unit, the electric heater (EH). EU is injected with the heat carrier (HC) in the form of gas flow in the form of pre-treated gas with the pre-set parameters and chemical composition corresponding to the products of combustion of burned fuel in the gas generator chamber, the pre-set interaction conditions in the zone of contact of HC with the liquid surface are provided, temperature and pressure are measured in various points, from the thermal sensor the signal is generated into the logic unit, the signal from the thermal sensor is compared with the pre-set signal for EH switching on or off, EN is switched on or off depending on weight coefficients, deviations of HC current temperature, rates of HC cooling and temperature increase, the stationary mode of average temperature of systems is achieved, HC supply into EU is stopped.

EFFECT: invention allows to improve the experimental accuracy of gasification process.
